I do think Boeser is the young piece to potentially shop, to bolster the blueline long-term. He's got the sort of "value" to actually fetch something resembling what the Canucks desperately need. And his nature as a kind of frustrating, streaky "pure sniper" makes him more palatable to move. But it'd definitely hurt, losing that pure finishing ability. One of those things that can be hard to appreciate, until it's gone.
It'd have to be a 1-for-1 sort of swap for a really good young defenceman. And that sort of deal is probably tough, because what teams genuinely have a real "surplus" of quality young defencemen to deal from?
